First thing. That is people's problem, not directly TED's.

And TED's talks are not focus on science divulgation. All TED talks can basically be stored in either the 'Look what I'm doing' bag or 'This is what happened to me' bag.

I have yet to see a talk where the main focus was to teach a concept rather than explaining it very superficially in order to introduce an idea based on that concept.
